测量偏倚

Kappa受实验对象底分布及测量偏倚影响较大，在进行一致性分析时，建议计算多个指标，进行综合评价。

Kappa is influence by the original distribution of subjects and bias of raters , so multiple indexes should be calculated in measuring agreement .

由于纳入研究存在选择性偏倚和测量性偏倚的高度可能性，势必影响结果的证据强度，期待高质量的随机双盲对照试验提供高质量的证据。

Owing to high possibility of selection bias and measurement bias in included studies , there must be a negative impact on evidence intensity of our results . We expect best evidence from with high quality double blind randomized control trials .
